The invention discloses a scour-resistant filter for an oil field. The scour-resistant filter for the oil field comprises a casing, a spindle, a lifting motor and a stirrer, wherein a filtrate inlet is formed in one side of the upper part of the casing, a clean water outlet is formed in the other side of the upper part of the casing, an annular through groove is formed in the middle-upper part of the casing, a filtering filler inlet and outlet port is formed in one side of the middle of the casing, an observing hole is formed in the other side of the middle of the casing, a power device is arranged in the middle of the upper part of the casing, an antiseptic film is arranged on the outer wall of the casing, a baffle is arranged on the spindle, and a filter net is further arranged above the baffle. By means of the arranged filter net, on one hand, impact of a filtrate to the baffle can be reduced, and the lifting motor works more stably; on the other hand, silky substances and large particles in the filtrate can be filtered, the filtering filler is easier to clean, and the use amount of the filtering filler is reduced; meanwhile, in consideration of the working strength and durability of the filter net, a filter net manufacturing material is specially manufactured, so that the adaptability of the filter net is higher.
